What Is the Value of an Existing Forest Stand?

pine trees

Traditionally, the land expectation value (LEV) formula, the present value of perpetual cash inflows of timber revenues minus the present value of cash outflows of costs, has been employed as the main indicator of the value of a forest investment. However, when a forest stand is already established, the LEV approach is incomplete because it applies only to bare land. Thus, it is necessary to determine the value of a property with an existing forest stand. This 3-page fact sheet written by Andres Susaeta and Chris Demers and published by the UF/IFAS School of Forest Resources and Conservation provides the formula to determine the value of an already established forest stand at any stage of its development. This approach, known as the forest value formula, includes the value of the timber and the land. It can be used to compare the value of the stand when it is immediately harvested or when it is economically immature.

Would a forest landowner be economically better off growing a forest for pulpwood production with a short rotation instead of growing the same forest for sawtimber production with a longer rotation? To help answer this and related questions, this 4-page fact sheet written by Andres Susaeta and Chris Demers and published by the UF/IFAS School of Forest Resources and Conservation presents two approaches to determine the profitability of a forest stand. The net present value (NPV) of a single rotation provides the criterion to choose between different forest project investments of equal lives, whereas the equivalent annuity approach (EAA) is employed when forest project investments have different time lengths.

This 3-page fact sheet written by Byron Love, Michael Andreu, and Chris Demers and published by the UF/IFAS School of Forest Resources and Conservation summarizes a study to determine whether landowners may gain increased economic returns if they mark the first thinning in a southern pine stand. The study found that marking can indeed bring higher revenue at final harvest. The greater number of high-quality and faster-growing trees remaining after a marked thinning is the main reason for immediate and future increases in value.

Florida Trees Store Carbon in Forests and Wood Products

Pine trees in a forest-- Tyler Jones

Trees store carbon as they grow and produce wood. Carbon, and carbon storage in particular, have become important topics as policymakers, scientists, and industry leaders consider how to address the increasing amount of CO2 in our atmosphere. Because it changes the composition of the atmosphere, CO2 is a leading contributor to climate change. This 4-page fact sheet written by Adam Maggard, Leslie Boby, and Martha Monroe and published by the UF/IFAS School of Forest Resources and Conservation explains how storing carbon in living trees and in long-lasting wood products such as lumber and furniture can reduce atmospheric CO2. Florida’s forest and wood-product industries are worth billions of dollars. Clean water, wildlife, and other benefits add to the value and importance of these forests.

Biscogniauxia (Hypoxylon) Canker or Dieback in Trees

Biscogniauxia canker or dieback is a common contributor to poor health and decay in a wide range of tree species growing in many different habitats, such as forests, parks, green spaces, and urban areas, in Florida. This disease is caused by several species of fungi in the genus Biscogniauxia (formerly Hypoxylon). These pathogens do not typically harm healthy and vigorous trees, but once they infect trees under stress from drought, root disease, soil compaction, construction damage or other causes, they can quickly colonize the tree. Once a tree is infected and fruiting structures of the fungus are evident, the tree is not likely to survive, especially if the infection is in the trunk. This 3-page fact sheet written by Claudia Paez and Jason Smith and published by the UF/IFAS School of Forest Resources and Conservation explains the pathogen’s biology and lists signs and symptoms as well as control measures and ways to keep trees healthy to resist infection.

Animals in Florida provide a variety of benefits to people, from recreation (fishing, hunting, or wildlife viewing) to protection of human life and property (oysters and corals provide reef structures that help protect coasts from erosion and flooding). By measuring the economic value of these benefits, we can assign a monetary value to the habitats that sustain these species and assess the value that is lost when development or other human-based activities degrade animal habitat. This 5-page fact sheet written by Shelly Johnson, Timm Kroeger, Josh Horn, Alison E. Adams, and Damian C. Adams and published by the School of Forest Resources and Conservation presents the results of a study that assessed the value of protecting five animal species in Florida and showed the economic value of protecting animal habitat.

Timber Production in a Working Forest Context

Florida forests

Working forests are private forests managed not just for timber production but also for a host of valuable ecosystem services like providing for recreation, maintaining habitat for wildlife, and maintaining a healthy watershed. Timber production is an essential ecosystem good or service that supports a number of important industries and provides jobs in Florida. This 6-page fact sheet summarizes the results of several studies to help forest landowners and other stakeholders understand how multiple-use management affects both timber production and other ecosystem services.

Carbon Stocks on Forest Stewardship Program and Adjacent Lands

Pine trees in a forest

Nonindustrial private forestlands in Florida provide many environmental benefits, or ecosystem services. Ecosystem services are benefits from nature that are directly enjoyed, consumed, or used by humans, such as water quality improvement or protection, recreation, biodiversity, and even timber. Another benefit from forests that is gaining interest is their ability to store carbon through the photosynthetic capture of carbon dioxide, a greenhouse gas, in tree, plant, and soil biomass. The carbon dioxide that is stored over the life of a forest, called carbon stocks, is not only important for mitigating greenhouse gas contributions to climate change, but it can also be valued in several markets and incorporated into environmental policy instruments. This 5-page fact sheet was written by Nilesh Timilsina, Francisco J. Escobedo, Alison E. Adams, and Damian C. Adams and published by the UF Department of School of Forest Resources and Conservation April 2017.
